I exclusively BF 3 babies, and each time gained approx 50 lbs during pregnancy. Each time, I was between 9 and 12 months postpartum before it really started coming off. Of course, you should eat somewhat healthy, and try to get in some exercise. It's actually hard for me to post that because I hate exercise, and am NOT prone to partaking regularly. That said, even getting out for a brisk walk with baby in stroller is great for both of you. I do remember doing that a lot with my first in a cheap jogging stroller. No other kiddos to take along, and the pneumatic tires on a stroller make it so much smoother to push, and ride in. If this is your first, relish it. Be patient with yourself, and good luck!
